... the estimation of the sparse reflectivity from seismic data and eliminate the noise. Secondly, a filter is applied on the amplitude spectra of the reflectivity to exclude the frequency information with low reliability. At last, the inverse Fourier transform is applied to obtain processed seismic data. The method...

... ABSTRACT Estimating based on downgoing waves in VSP data can be challenging when scattered waves from near-borehole velocity/density anomalies interfere constructively and destructively with the direct arrivals. The wavefield interference leads to modulations in amplitude spectra...
